I can do vector format logos, I'm no superstar but I can give it a go if you would like! Send your designs to lachystv@gmail.com and I'll do my best. I'm based in NSW and have experience with wide format printing. I use Adobe Illustrator which is the industry standard.

In case you didn't know the difference between Vector and Rastor (your normal JPEG, png sort of format) vector images when resized don't change at all in quality as they are a mathematical equation of lines and shapes instead of Rastor where resizing decreased quality dramatically. This is good as once your logo is done it can be placed on anything from a model train to an a380 aircraft without losing quality when resizing.

Ps although basic my "L" logo was created in vector and then converted to Rastor
